nice looking part! you would need to tune for this mod correct or no?

 

Everything would transfer to the new TB. You'll be all set from there.

 

What is the stock TB size? Anybody know, Are they all the same 4.8,5.3 or 6.0.

 

If we dont see the 8-10rwhp can we get a refund???

 

How would you "transfer" anything from the newer trucks TBs? They aren't serviceable like the vettes. Does this BBK have a motor?

 

It does not look to have the motor in the pic. And a 03 and 04 from GM are different also.

 

I've never taken a good look at the late model throttlebodies to notice if they come apart but I have taken 8.1 TBs apart and the 1756 pictured above will fit an 8.1. Everything usually swaps over.

Can't do that. Most parts don't have a performance guarantee.

 

You will need a special tool to swap the motor over. At least I did on my 02 drive-by-wire TB when I bought the Shaner TB. It's called a security Torx. Like a normal Torx socket but it has a hole in the middle to clear the raised center. I found a set at Sear's.

 

You won't be changing the 03+ year models out very easily. The unit is fully closed and held together with rivets. Take a look:
